    Abstract

    Enantioselective intramolecular cycloaddition of hexaynes with 1,3-diyne moiety was examined. Chiral Rh catalyst provided axially chiral 1,1′ -bis(biphenylenyl) derivatives by consecutive [2+2+2] cycloaddition. In contrast, chiral Ir catalyst provided axially chiral macrocyclic compounds with 1,3-diyne moiety by single [2+2+2] cycloaddition.
